ProjectEuler

It is nearly 3 years ago that I started woking on Problems from Project Euler. As a proof I uploaded all my java code to github back then. Sinds then I have tried many diferent languages and approaches. The problems can be found here:  https://projecteuler.net/archives
 
All programs without _Name are not solved jet. They are just there to share them between the different distro's I use.
